TYPEWRITING MACHINE.

Application filed March 31, 1922.

To all whom it may concern:

Be it known that I, JOHN A. VVrInnnY. a citizen of the United States, residing in New Orleans, in the parish of Orleans, and State of Louisiana, have invented certain new and useful Improvements in Typewriting Machines, of which the following is a specification.

This invention relates to typewriting machines, and particularly to means for en abling a condensed record-sheet or proofsheet to be inserted in the machine and detained therein in adjusted position while other work-sheets, such as bills, statements,

or ledger-sheets, may be inserted, positioned, typed upon and removed from the machine in succession one after the other, so that the items typed upon each of the several latter sheets will all appear seriatim upon 2 the condensed record-sheet.

The object of the invention is to produce a device, of the kind above noted, of simple and inexpensive construction, and which may be embodied in a usual or standard form of typewriting machine without the necessity of making any changes therein other than to install thereon the additional-parts required by the present improvement.

The invention comprises a bail pivoted upon the platenframe and carrying adjacent its ends paper-guiding and holding devices, such as pape'nfingers, to co-operate with the front and upper part ofthe platen for guiding an inner work-sheet, such as a condensed record-sheet, upwardly and.

rearwardly below and behind the front bar or front rod of the bail, upon which is mounted a gage for an outer work-sheet, such as a bill, a statement, or a ledger-sheet. 40 The usual releasable feed-rolls running upon the bottom of the platen are cast off, and the bail, together with the parts carried thereby, is swingable away from the platen to enable the inner sheet or condensed record sheet to be adjusted prior to the insertion of the first outer sheet. Said gage, which may be a side-edge gage, is pivoted on said front rod of the bail to swing away from the platen, so as not to obstruct the insertion of the inner sheet or condensed record-sheet, and to swing into proximity to the platen, so that the outer sheet, when inserted, may be directed upwardly at the front of said gage and the front rod of the bail, said outer sheet being thus inserted and adjusted while Serial No. 548,294.

part of the rear paper-table for feeding the j condensed record-sheet downward to the said usual lower feed-rolls and to the usual paperapron beneath the platen, said rear feed-rolls being also effective to co-operate with said paper-holding devices or paper-fingers at the delivery side of the platen to detain the condensed record-sheet in adjusted position in the machine during the insertion and positioning of the successive outer work-sheets.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a front elevation of the platenframe and parts carried thereby of an Underwood Standard typewriting machine, having the present invention embodied therein and showing the parts thereof in their effective positions. I

Figure 2 is a substantially central frontto-rear vertical section of what is shown in Figure 1, and further shows, in broken lines, the side-edge gage for the outer work-sheet as tilted rearwardly on the bail-rod to a position providing for the insertion of the inner or condensed record-sheet.

Figure 8 is a similar View, with the bail and parts carried thereby swung upward and rearward away from the platen to provide for adjusting the condensed recordsheet.

In carrying out the present invention, a wide inner sheet 1, which is a. condensed record-sheet or proof-sheet, is inserted at the introductory side of the revoluble platen 2 over an upper rear paper-table 3 having an upper straight part and a lower part curved around the upper part of the platen at the rear thereof. Theupper rear papertable 3 is rigidly supported upon the usual platen-frame by the end walls 4, in which the platen-axle 5 is journaled, by means of lugs or sleeves 6 on the rear paper-table 3, which are rigidly fixed, by means of set position, shown in Figures 1 and 2,

screws 7, upon the usual rear transverse tierod 8 which extends between andjtis-rigidly fixed in the upper part of the end walls 4 rearwardly from the top of the platen and above the rear part of the platen. The platen 2 is now rotated, either by the usual line-space mechanism including the linespace ratchet wheel 9, or preferably and more rapidly by means of the usual handle-knob 10, to feed the condensed record-sheet 1 downwardly at the introductory side of the platen, such feeding of this record-sheet 1 being accomplished by means of upper rear auxiliary or supplemental spring-pressed feed-rolls 11, which are mounted upon the paper-table 3 by means of spring arms 12 which pressthese rolls towards the platen through openings 13 provided in the lower curved part of the paper-tableB,

As the platen is rotated, the condensed record-sheet 1 is fed downward until its leading edge passes upon the usual curved paper-apron 14 beneath the platen. and ,be-

tween the platen and the usual normally effective releasable front and rear feed-rolls 15 which run upon the lower side of the platen. By continuing the rotation of the platen, record-sheet 1 will pass upward at the front or delivery side of the platen beneath curved paper-fingers 16, adjacent the ends of the platen, and beneath spring-pressed paperholding rollers 17 adjacent the upper parts of the paper-fingers, said paper-fingers 16 and rollers 17 forming paper-guiding and paper-holding devices for "the condensed record-sheet 1. The advancing condensed record-sheet 1 1s guided by the paper-fin ileath and to the rear of a rod or bar 18 extending along the top of the platen and which forms the front bar of a swingable bail having end arms 19 pivoted upon the rear tie-rod 8 just within the frame ends 4 of the platen-frame. The end arms 19, in which the frontbail-rod 18 is rigidly supported, have front end parts 20 turned.

over inwardly at the front of the bail-rod 18, the upper ends of the paper-fingers 16, as well as spring mountings for the rollers 17, being secured to these turned-over ends 20 by means of screws 21.

In order to position or adjust the con densed record-sheet to the desired writing position, the lower feed-rolls 15 are now released by means of a suitable cast-off de-. vice, not shown, and the bail, comprising the side arms 19 and front bar 18, is swung upwardly and rearwardly from the effective to the ineffective position shown in Figure 3, thereby leaving the condensed record-sheet 1 free to be easily straightened and adjusted, the light pressure thereon'of the rear upper feed-rolls 11 not interfering with such adthe leading edge of the condensed 'ers 16 around the platen. rearwardly bejustment. The swinging bail may be held at its forward position, in which the paperfingers 16 and rollers l7 are effective, by means of a curved leaf spring 22 carried within a U-shaped rear endpart 23 of one of the bail arms 19, for pressing a short rod or roller 24 into a groove formed along the" lower side of the tie-rod 8, as shown at the left in Figure 1. A similar holding device, not shown, is also preferably provided at the other side of the machine. Thesedevices will also be effective to hold the bail at the ineffective position shown in Figure 3.

After the condensed record-sheet 1 has been adjusted, the bail is swung forward from the Figure 3 to theFigures 1' and2 position, thereby rendering the paper-fin gers 16 and rollers 17 effective to co-operate with the rear upper feed-rolls 11 for detainingthe sheet1' in the machine and holding. it in its adjusted position. While the condensed record-sheet 1 is thus detained and held and with the lower feed-rolls 15 released, an outer narrower work-sheet. 25, which may be a billv or a statement or a ledger-sheet, is inserted at the introductory slde of the platen over a lower usual rear paper-table 26, which may form part of the platen-frame, and.

which, in the machine illustrated in the drawings, is shown as continuous or formed in oneplece wlth the paper-apron 14L The outer narrower work-sheet 25 is pushed.

around from the rear over the paper-apron 1 L beneath or at the outside of the C011. densed record-sheet 1 and above the released lower feed-rolls15 until its leading edge rises above the printing point on the platen,

indicated in Figure 2 bythetype-head 27 carried by the, swinging type-bar 28, and 1s .a'd usted'or straightened bymeans of the usual wing-scales, not shown. As theouter sheet 25 is further advanced, its leading edge will pass to the front of thefloor portion 29 of a gage-member or side-edge gage having an outstanding side flange 30 against which the outer work-sheet 25 may be gaged laterally at its adjacent side edge. This side-edge gage is carried by the front bar 18 of the swinging bail, and in the normal or effective position of the gage the lowe-r edge of its floor portion 29 rests in proximity to the front of the platen just above the printing line, as shown in Figures 1 and 2, so as to be effective toreceive and guide the advancing outer work-sheet 25.

To provide for the insertion of the inner condensed record-sheet 1, as hereinbefore described, the side-edge gage may be swung from its normally effective position, shown in Figure 1 and also shown in full lines in Figure 2, to an upper position thereof,

shown in broken lines in Figure 2, so as not to obstruct the leading edge of the advancing condensed record-sheet 1. Also during the adjustment of the condensed record-sheet 1, hereinbefore described, the side-edge gage for the outer sheet 25 swings with the bail-rod l8 upwardly and rear wardly to the position shown in Figure 3, so as to be entirely out of the way. In order to provide fonswinging the side-edge gage between the two positions thereof, shown in Figure 2, it is pivoted on the bailrod 18 by means of a U-shaped portion, coinpiising ears 31 and an upper connecting member 32, which is joined by means of an intermediate connecting portion 33 to the upper end of the floor portion 29 of the gage. The entire gage-member may be formed from a single piece of sheet-metal, as shown in Figures 2 and 3. The gagemember or side-edge gage may be slid along the bail-rod 18 between the paper-fingers 16 for adjusting it to different gaging positions. For frictionally holding the gage at its different positions of adjustment and also for holding it at its effective position, shown in Figures 1 and 2, as well as for friction-ally detaining it at the ineffective position shown in broken lines in Figure 2, a bowed leaf spring 34, interposed between the ear-connecting member 32 and the bailrod 18, presses a small detent roller or rod 35 against the bar 18, and in the effective or gaging position of the gage presses this roller or rod 35 into a grooveextending along the top of the bail-rod 18 throughout its length, as shown in Figure 2, for thereby more securely holding the gage at the gaging position. Of course, a carbon-papersheet will be interposed between the worksheets 1 and 25 and may be conveniently inserted along with the condensed record-sheet 1, and the forward end of the carbon-sheet may be folded over the leading edge of the condensed record-sheet 1 in order to facilitate the insertion of these sheets.

During the insertion and adjustment of the outer work-sheet 25, as above noted, the inner condensed record-sheet 1 and its accompanying carbon-sheet are securely held in position in the machine by means of the upper rear feed-rolls 11 and the front paperholding devices comprising the paper-fingers 16 and rollers 17. When the outer worksheet 25 has been adjusted, as above noted, the lower feed-rolls 15 are thrown on or made effective and the typing may proceed, all the sheets being advanced or line-spaced by means of the usual line-space mechanism. Should the outer work-sheet 25 show any tendency to curl or fall over forwardly away from the floor 29 of the side-edge gage, such tendency may be prevented by bringing into use the usual paper-guiding finger provided upon the Underwood machine to engage the paper adjacent to the printing point, or, 1f desired, the gage may be swung upward on the bail-rod 18 to the broken-line position thereof, shown in Figure 2, and the upper end of the outer sheet 25 may then be passed upward to the rear of the bail-rod 18, but preferably is kept at the front.

Obviously, in the carrying out of the invention, as illustrated in the drawings, the outer work-sheet 25 will be an original or ribbon copy while the condensed recordsheet 1 will be a carbon copy forming a record of all the items typed upon the successively inserted outer sheets. After the item or items which are to appear up on the outer work-sheet 25' have been typed thereon, the lower feed-rolls 15 are cast off or released and the typed outer sheet 25 is then withdrawn from the front of the machine, while the inner condensed record-sheet 1, containing a carbon record of what has been typed upon the outer sheet 25, is detained in the machine and held therein in adjusted position by means of the upper auxiliary or supplemental feed-rolls 11 and by the paperholding devices at'the delivery side ofthe platen comprising the paper-fingers 1G and pressure rollers 17. \Vhile the inner condensed record-sheet is thus securely detained in position in the machine, another outer sheet is inserted and positioned in the manner above described for the first outer sheet 25, and this last-inserted sheet is then typed upon and removed similarly to the first outer sheet 25, and so on successively for any number of outer sheets of which it is desired to make a carbon record upon the condensedrecord-sheet 1. It is understood, of course, that after any outer sheet has been gaged and the lower feed-rolls 15 made effective, all of the sheets may be line-fed forward to any extent desired or required by operating the usual line-space mechanism. Also, in case additional space is desired between the successive entries on the condensed recordsheet 1, this sheet may, in the usual way, be independently line-spaced to the desired extent between the times of the insertion of the successive outer sheets.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
